Abstract
Feeding preterm infants can be a challenge due to gastrointestinal (GI) immaturity which can lead to feeding intolerance, malnutrition, and poor neurodevelopment. Currently there is no non-invasive and quantitative method to determine GI maturity in infants. Electrogastrography (EGG) provides a non-invasive method of measuring gastric myoelectrical activity and has been used on adults to determine gastric abnormalities. EGG was explored as an option for determining GI maturity in preterm infants by quantifying the power spectral density (PSD) of EGG data and its spectral means. The power spectral density and spectral means were calculated during three gastric rhythm (GR) bands (mPSDgr) pre-, during, and post feeding to explore the relationship between EGG and the gastrointestinal development process.
